Bayern beat the Gunners 10-2 over two legs after a second 5-1 win on Tuesday night, the Germans scoring all their goals in the second half after the hosts imploded following Laurent Koscielny's sending-off.
The German champions' English language Twitter account was just as brutal, tweeting: 'What time is it? Yep, it's ten to!', referencing the aggregate score.
Arsene Wenger reacts as he watches Arsenal crumble to a 5-1 defeat against Bayern Munich
The Arsenal players were overwhelmed by Bayern who won the tie 10-2 on aggregate
Bayern have some form when it comes to roasting Arsenal on social media - following their 5-1 victory in the first leg, they wrote: 'Same again next year?'
As it was, Munich did not have to wait a year, only a fortnight, before taking the chance to completely humilate Arsene Wenger's team.
The joke went down well on Twitter, garnering over 11,000 retweets and 10,000 likes in two and a half hours, and led a stream of cheeky humour at the north Londoners' expense from across the website.
Some went for puns, along the lines of 'What happens when we play Bayern? - Well, we 10-2 get hammered', 'How do Arsenal do in Europe? They 10-2 get knocked out', and 'Arsenal don't need 11 on the field to lose 5-1. They can do it with 10-2.'
Others pointed out the Gunners' remarkable consistency in Europe - being knocked out in the last 16 in the Champions League in each of the last seven seasons.
For Arsenal fans however, there could be few words apt enough to describe one of the worst nights in the history of the club.
